As always, swift, thoughtful, and helpful replies.
HOWEVER, still having major issues trying to get RELIABLE communications to unit, as well as just about any CNC sender s/w which will work on cheap little win10 tablet. (Done lugging laptop out to shed, that is just too many issues all the way around.)
Have -I think- ‘tried’ just about every freebie sender s/w out there (installed java and python to do so, and STILL trying to track down necessary python libraries which evidently aren’t named what they once were), and have had only ONE which works with any consistency, and it is not 100%
Source Rabbit’s g-code sender will drop communications a handful of times when jogging to zero out, but is about the onliest program I can get to work at all. Others are either complaining about missing DLL’s (sigh), or python libs, or opens up okay, but won’t connect, or connects, but won’t control, etc, etc, etc.
Turns out, NOT the CNC, NOT the ArcCam s/w, NOT anything else, but simply getting the dog damn g-code off the dog damn tablet to the dog damn CNC has caused me more headaches than anything else.
IF I am not mistaken, I have downloaded grbl-gru as well, but it has some issue or another. (They are all blurring together at this point, have tried at least a dozen or more progs.)
